Borneo rainforest. Some tropical forest types are difficult to categorize. While forests in temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. [1] There is no single scheme that defines what a forest is, in tropical regions or elsewhere.
Tropical and subtropical coniferous forests are characterized by diverse species of conifers, whose needles are adapted to deal with the variable climatic conditions. [1] Most tropical and subtropical coniferous forest ecoregions are found in the Nearctic and Neotropical realms , from Mexico to Nicaragua and on the Greater Antilles , Bahamas ...
Tropical seasonal forests, also known as moist deciduous, monsoon or semi-evergreen (mixed) seasonal forests, have a monsoon or wet savannah climates (as in the Köppen climate classification): receiving high overall rainfall with a warm summer wet season and (often) a cooler winter dry season. Some trees in these forests drop some or all of ...
Tropical species have experienced a longer and less disturbed evolutionary history than species found in other biomes around the world. Therefore, temperate species that initially radiated out of tropical biomes are often nested in the phylogenies of tropical clades. The consistency of tropical environments constitutes species composition with ...
Forests have an enormously important role to play in the global ecosystem. Forests produce approximately 28% of the Earth's oxygen (the vast majority being created by oceanic plankton), [3] they also serve as homes for millions of people, and billions depend on forests in some way. Likewise, a large proportion of the world's animal species live ...
The moisture from the forests is important to the rainfall in Brazil, Paraguay, Argentina [45] Deforestation in the Amazon rainforest region was one of the main reason that cause the severe Drought of 2014–2015 in Brazil [46] [47] For the last three decades, the amount of carbon absorbed by the world's intact tropical forests has fallen ...
The crowns of the dominant trees receive most of the sunlight. This is the most productive part of the trees, where maximum food is produced. The canopy forms a shady, protective "umbrella" over the rest of the forest. Emergent layer exists in a tropical rain forest and is composed of a few scattered trees that tower over the canopy. [39]
Threats to the rainforests include destruction and fragmentation of forests by commercial logging, oil palm plantations, and mining. The bushmeat trade and poaching is depleting the rainforests of wildlife. [2] With annual forest loss of 0.3% during the 2000s, [5] the region had the lowest deforestation rate of any major tropical forest zone. [6]
